MONITORING WATER QUALITY IN VEGETABLE HYDROPONICS USING ARDUINO MICROCONTROLLER

pH stands for the power of Hydrogen, which is an important factor in hydroponic systems. The hydrogen ion concentration determines the value of the acidity in the solution. If the pH value of the solution is below 7.0, then it is called acidic, and if the pH value is above 7.0, it is called alkaline. The pH value can change, so it is necessary to pay attention to the acidity of the water so that the roots absorb nutrients properly that farmers often find it difficult to take measurements. Mustard plants have a pH range of 5.5 – 6.5. Based on the pH range, it is necessary to have a tool to monitor the quality of the pH in mustard plants. This monitoring is carried out by creating a hydroponic nutrient water disposal system by combining agriculture and mechatronics. Mechatronics will control the nutrient distribution system so that it can be monitored with a smartphone via wireless connectivity such as the GSM module (800L. The water quality monitoring system works by using ultrasonic sensors, sensor probes and TDS sensors, as well as the GSM 800L module. monitoring of water quality in hydroponic mustard plants) using an Arduino microcontroller and detecting pH conditions and solute content. As for the disposal of nutrient water, using a water pump connected to the microcontroller via a relay. Based on the prototype carried out on June 26, 2021, the condition of water quality has decreased in nutritional quality with the first data (pH 6.31 solute 529 ppm) and the latest data (pH 9.09 and solute 662 ppm). When the water quality is below the nutritional standard, the water pump turns on to remove the nutrient water. The results of the prototype that has been carried out have succeeded in monitoring water quality hydroponics and can be used by farmers

ANALISIS KESALAHAN BERBAHASA SURAT KABAR JAWA POS RADAR SOLO PADA RUBRIK TREVELLING EDISI BULAN JANUARI - MARET TAHUN 2020

Newspaper is a print media that functions to provide information, which is written according to gifts and language rules (Indonesian language). in this study examines and analyzes language errors in the Jawa Pos Radar Solo newspaper in the January-March edition of the Trevelling rubric in 2020. The type of research used is descriptive descriptive research. the technique used is refer to the one used to obtain data and record it to record the acquisition of data. based on the results of the study found errors in the spelling level language in the form of errors in writing words, mistakes in capital letters, errors in commas, errors in writing numbers, errors in the use of periods and colons, andparticle use error.errors at the level of syntax in the form of morphological manifestations are errors of suffix, perfix errors, and reduplication errors. errors at the level of discourse in the form of misuse of references and errors there are several topics in one paragraph

DETECTION AND PATHOGENICITY LEVEL SCREENING OF HEMOLYTIC BACTERIA ISOLATED FROM UNPACKED CHICKEN NUGGET : Received: 04th October 2023 Revised: 13th October 2023, 02nd November 2023, 06th November 2023 Accepted: 08th November 2023

Food poisoning is a severe threat that can lead to death. According to the WHO, cases of food poisoning have been on the rise in recent years. Pathogenic bacteria are responsible for food poisoning, often originating from contaminated food. Chicken nuggets, a popular ready-to-eat food, are susceptible to bacterial growth due to the risk of microbial contamination during storage. This study aims to assess the pathogenicity levels of bacteria in chicken nuggets when stored at room temperature for seven days. Samples from chicken nuggets left at room temperature were diluted and cultured on Nutrient Agar (NA) media. Subsequently, bacterial pathogenicity screening was conducted using MacConkey Agar (MC), Blood Agar Plate (BAP), and Chocolate Agar Plate (CAP). The results revealed six bacterial isolates labeled FMCN-1 to FMCN-6 (FMCN denoting Fatmawati Market chicken nugget). Most isolates exhibited a moderate level of pathogenicity (FMCN-2, FMCN-3, FMCN-4, FMCN-5, and FMCN-6), with only one isolate demonstrating low pathogenicity (FMCN-1). In conclusion, storing chicken nuggets at room temperature for seven days can lead to bacterial contamination with mostly moderate pathogenicity. Further molecular analysis is required to identify the potentially harmful bacteria
